Three-segment profiled H-shaped steel rapid saw cutting device and method

Abstract

The invention discloses a three-segment profiled H-shaped steel rapid saw cutting device, which comprises a sawing machine provided with a circular saw web, wherein a loading workbench is arranged at the bottom of the sawing machine; a roller path is formed on the loading workbench; a horizontal saw web for cutting an H-shaped steel web plate and vertical saw webs for cutting an H-shaped steel flange are arranged on the sawing machine; the vertical saw webs are arranged on both sides of H-shaped steel respectively; the horizontal saw web is arranged between the two vertical saw webs and above the H-shaped steel; and the three blades are arranged on the same plane. The saw cutting device provided by the invention has the advantages of simple structure, convenience for operating, low manufacturing cost and high saw cutting precision; and a method for performing rapid saw cutting on the H-shaped steel by using the device is simple, the conventional discontinuous saw cutting is replaced by three-segment continuous cutting, the cutting difficulty is lowered, and the saw cutting stability is improved.

Description

technical field [0001] The invention relates to a sawing device and a sawing method, in particular to a three-stage imitation form H-shaped steel rapid sawing device and method for processing H-shaped steels for resizing. Background technique [0002] H-shaped steel is an economical cross-section steel, which is widely used in construction, machinery and other industries. In addition to the need to use large-diameter cold-cut saw blades for sawing, more sawing processes occur in offline sawing, including the re-sizing processing of the section steel factory itself, and the sizing processing of the steel structure factory and machinery factory. [0003] At present, the commonly used sawing methods for H-shaped steel are band saw sawing and large-diameter circular saw sawing. The cost of band saw cutting equipment is low, but its average single cutting time is about 25 minutes, and the work efficiency is low; large-diameter circular saws are divided into ordinary high-speed c...

AI Technical Summary

Problems solved by technology

The cost of band saw cutting equipment is low, but its average single cutting time is about 25 minutes, and the work efficiency is low; large-diameter circular saws are divided into ordinary high-speed cold saws and carbide saws, and the high-speed cold saw equipment is huge , high noise, not suitable for offline cutting; large-diameter carbide saws have good cutting quality, low noise, and high efficiency, but the equipment is expensive, the transportation cost is high, and the application range is small
